いた。[0003] The airbag is provided with an inflation chamber for inflating the inflation gas by inflow, and a gas flow path for guiding the inflation gas to the inflation chamber. The expansion chamber is composed of a front-seat expansion chamber and a rear-seat expansion chamber so as to be disposed on the side of the front seat and the rear seat. Further, each of the inflation chambers is configured to connect the inner side wall portion and the outer side wall portion of the airbag, and a plurality of inflatable portions are arranged along the gas flow path by non-inflatable portions that do not allow inflation gas to flow.

した可撓性を有する布製としていた。A flexible inner tube for guiding the inflation gas is provided in the gas flow path (see FIGS. 9 and 10 in the above publication). In the inner tube, a supply port capable of supplying an inflation gas into the inflation portion is opened so that the inflation gas can be supplied quickly or in a predetermined inflation portion so that each inflation chamber can be inflated evenly. I was The inner tube is made of a flexible cloth made of the same material as that of the airbag so as not to be bulky when the airbag is folded.

The flow rate of the inflation gas passing through the supply port may be increased, and there is a possibility that the inner tube may not be meaningful.

A gas flow path that guides the inflation gas to the expansion chamber, wherein the expansion chamber includes a plurality of expansion portions disposed along the gas flow path, and in the gas flow path, A head provided with a flexible inner tube capable of guiding the inflation gas, and a supply port capable of supplying the inflation gas in the inflation portion being opened in the inner tube; An airbag for a protective airbag device, wherein a reinforcing portion is formed by suturing a suture around a peripheral edge of at least one supply port of the inner tube.

でも、その体積を殆ど増加させず、エアバッグの収納性
を阻害しない。In the airbag according to the present invention, a suture is sewn to the periphery of the supply port of the inner tube to form a reinforcing portion, and the suture opposes the tearing force acting on the periphery of the supply port. Therefore, since the tearing strength of the periphery of the supply port is improved by the reinforcing portion, even if the inflation gas passing through the supply port becomes high pressure, the breakage of the periphery of the supply port is suppressed, and the supply port is expanded. Opening can be prevented.
In addition, the reinforcing portion is obtained by merely suturing a suture to the periphery of the supply port. Even if the airbag is folded together with the inner tube, the volume does not substantially increase, and does not hinder the storage capacity of the airbag.

収納性を阻害する虞れを極力低減することができる。Further, when the reinforcing portion is formed by sewing a flexible reinforcing material on the periphery of the supply port, the reinforcing portion is formed only by a suture. Compared with the case of the configuration, since the reinforcing material sewn to the suture also counters the tearing force acting on the peripheral edge of the supply port, the strength of the peripheral edge of the supply port can be further improved. In addition, although the volume of the inner tube folded together with the inner tube is slightly increased by the volume of the reinforcing material, the reinforcing material itself has flexibility, and the reinforcing material is provided only near the periphery of the supply port. By arranging, it is possible to reduce as much as possible the risk of impairing the storage ability of the airbag.

れを、一層、低減することができる。In the case where the reinforcing member is sewn to the periphery of the supply port in a substantially annular shape as described in claim 3, the reinforcing member is disposed only on the periphery of the supply port. Even if the reinforcing member is provided, the possibility of hindering the storage ability of the airbag can be further reduced.

る。According to a fourth aspect of the present invention, the reinforcing member is formed of a sheet material which is disposed on the periphery of the plurality of supply ports and has a through hole communicating with each of the plurality of supply ports. In comparison with the case where a substantially annular reinforcing material is arranged on the periphery of each supply port, the volume of the airbag folded together with the inner tube increases by the amount of the reinforcing material between the supply ports, Since the reinforcing members can be collectively arranged at the positions of the individual supply ports, and the displacement is unlikely to occur, the sewing operation of the reinforcing members can be performed efficiently.

Even if a tearing force acts on each supply port peripheral edge 32, the suture S
And each through-hole 3 of the reinforcing material 35 sewn with the suture S
Since the tearing strength of the peripheral edge 32 of each supply port 31 is enhanced by the reinforcing portion 33 against the peripheral edge of the supply port 5a, even if the inflation gas G passing through the supply port 31 has a high pressure and a high temperature. The breakage of the supply port peripheral edge 32 is suppressed, and the supply port 31 can be prevented from expanding.

Each of the supply members 31 is formed from a sheet material, and each of the supply members 31 is provided with an annular reinforcing member 37 on the peripheral edge 32 of each of the supply ports 31 as in an inner tube 30B shown in FIGS. Although the volume of the folded inner tube 30 is increased by the material of the reinforcing material 35 between the ports 31, the reinforcing material 35 can be collectively arranged at the positions of the plurality of supply ports 31, and the displacement is reduced. Since it is unlikely to occur, the sewing operation of the reinforcing member 35 can be performed efficiently.

Then, only the suture S is sewn to form the reinforcing portion 33A. Also in this case, the suture S is sewn so as to surround the supply port 31 in a multiple annular shape around the supply port 31. In addition, if both edges 29a and 29b of the band-shaped material 29 are sewn after forming the reinforcing portion 33A, the inner tube 30A can be manufactured.
